Hi, it's my first post here in watchrepairtalk. I'm trying to get a Seiko 4336 quartz working again and having trouble with the date setting mechanism. Although this is a quartz watch I believe the parts are similar to mechanical Seikos of the 70s era. I'm sorry I don't know the part names. I have the technical document for this movement but the part names are not clear on it. Anyway, when turning the crown counterclockwise the gear on the right doesn't engage the gear on the left (in blue circle), which should turn the day wheel. I can get the left gear to turn partially if I align it just so, but it won't even make a complete revolution. Shouldn't it turn continuously as I turn the crown? I can't work out if I have some sort of alignment problem or if the parts are worn, or something else. I thought maybe it would work properly when the day wheel was in place but no dice. I should add that I didn't ever take these parts off the watch when doing my clean and so on.

I'm new to the site and relatively new to watch repair. I work part time for a jeweler. I'm currently working on a VD85 and I'm not sure about indexing the "Day" hand. I broke the stem and have to retrieve it before continuing. Can anyone offer advice on either. Thanks in advance, Dave.
